Which change in gas levels activates breathing and prevents you from holding your breath forever? What structural features of the lung and cardiovascular system contribute to effective gas exchange? Expiratory reserve volume is the maximum amount of additional air that can be forced out of the lungs after a normal breath. There will be more capillaries present so the quicker the oxygen will get to the muscles. Expiratory reserve volume decreased with exercise because greater respiratory effort forced more air out of the lungs with each exhalation. Why do our muscles need it? Explain what happens to the respiratory rate (breaths per minute) during exercise and what happens to the respiratory rate during the resting period after exercise. c. If one of the lungs collapses due t. Critically discuss. This air cannot be expelled and it helps keep the alveoli (the small air sacs that make up the lungs) open at all times.

How would the volume of lung measurements change if the data was collected after vigorous exercise? Explain this reasoning and discuss any risks that may be posed by this practice. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. What is vital capacity and how do you calculate it? Vital capacity is the maximum amount of air that can be breathed out after breathing in as much air as possible. IC increases with exercise because the body needed more oxygen. Fill in the blank. Small children certainly do need careful supervision. Another systematic error may include the rate of perceived effort. As the intensity of exercise increased, so did the rates of the heart and breathing. Residual lung volume increases. 8.

How does vital capacity of the lungs change with age? Then indicate the way in which who or whom is being used in the Why or why not. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles need for oxygen and energy will be smaller than during exercise. The FRC decreases because the body of making itself breath more rapidly. What happens to pCO2 during rapid breathing?

TV, ERV, IRV, RV, IC, FRC, VC, TVC, Minute ventilation. Explain why VC does not change with exercise. It is further pointed out that the heart is another limiting factor because it determines how much blood and oxygen are supplied to the muscles especially when blood flow exceeds maximal cardiac output (Bassett & Edward, P6- follows guidelines to interpret collected data for heart rate, breathing rate and temperature before and after a standard period of exercise. Fiber adsorbs (binds) bile so eating a fiber-rich (high fiber) diet would result in more bile binding to fiver and more bile excreted in feces. In healthy individuals, exercise produces either a mild bronchodilatation, facilitating an increase in airflow without a significant increase in airway resistance and the work of breathing, 1 or has no effect. This causes more oxygen to dissociate from What is pneumothorax and how does it develop?
